Abstract (en)

[origin: EP3876665A1] A user apparatus includes a control unit configured to determine a spatial reception parameter of a control channel based on QCL (Quasi-co-location) information pertaining to a synchronization signal or a reference signal, and a receiver configured to receive the control channel based on the determined spatial reception parameter, wherein, in a case where a first search space is received during a non-contention based random access procedure, the control unit determines the spatial reception parameter of the first search space based on the QCL information applied when receiving an instruction by the control channel, the instruction triggering the non-contention based random access procedure.
